Overview
The PT-1407T is an externally driven piezoelectric buzzer transducer manufactured by Soberton Inc. It operates at a nominal voltage of 5 V with a current consumption of 5 mA. The device produces a sound pressure level of 85 dB at 5 V measured from a distance of 10 cm. Its resonant frequency is 4 kHz. The component features PC pin termination for through-hole mounting and has a diameter of 13.8 mm. It is designed for operation within a temperature range of -20°C to +70°C.
Feature Summary
- Externally driven piezoelectric design requiring external drive circuitry
- Through-hole PC pin termination for standard PCB mounting
- Washable construction suitable for manufacturing processes
Applications
- General purpose audible alarms
- Electronic device status indicators
- Security system sirens
Procurement Notes
Verify the specific suffix 'T' indicates the tape-and-reel or specific packaging variant if required, as datasheets may list base part numbers like PT-1407. Confirm RoHS compliance status with the supplier. Ensure the external drive circuit matches the 5V/5mA specification. Check for washable compatibility if post-soldering cleaning is part of the assembly process.
Selection Notes
Select this component when an externally driven solution is preferred over active buzzers for cost or flexibility reasons. The 5V nominal voltage suits standard logic-level circuits. The 85dB output provides sufficient audibility for general alerts. Consider the 13.8mm diameter for spatial constraints on the printed circuit board layout.
Part Context
This part belongs to the Soberton PT series of piezoelectric buzzers. These components are passive transducers that convert electrical signals into sound via mechanical vibration. The series typically offers various frequencies and sound levels to meet different acoustic requirements in consumer and industrial electronics.
Replacement Considerations
Direct substitutes include other externally driven piezo buzzers with similar 5V ratings and 4kHz resonance. Verify mechanical dimensions (13.8mm diameter) and pin spacing for compatibility. Ensure the replacement supports washable processes if applicable.
